Duels

Players must beat each player in a stage 5 times (or more in some stages), in order to get to the next stage. Once the player beats a character 5 times, he or she may keeping on dueling them for more points. Here are the list of characters that a player may duel against (the characters are the same in the 3 versions):

Format

During gameplay there is more than one way to win. A player may win by decreasing the opponent's life points to zero, forcing your opponent to run out of cards (have them unable to draw a card at the start of their turn), or by having all five pieces of Exodia in your hand.

In order to duel, a player's Deck must contain exactly 40 cards and be under their current Duelist Level. If the Deck is over/under 40 cards or over the Deck limit cost, the player will not be able to duel until the error is fixed.

However, in Yu-Gi-Oh! Duel Monsters 4: Battle of Great Duelistmonsters can be destroyed because they have an inferior Alignment (which substitutes Attribute in this game). In this format, the difference between Attack or Defense points does not matter and the card with the inferior alignment is instantly destroyed. The exception to this rule is when the monster with the superior alignment also has higher attack points (when attacking) or defense points (when being attacked in Defense position), in which case Battle Damage is calculated normally. However, when a Defense positionmonster is attacked by a monster with an inferior alignment, the monster with the inferior alignment is destroyed.

Fusion

Since "Polymerization" is not included in this game, Fusions occur differently; selecting one card and placing it on top of another compatible card could result in a fusion for an entirely different monster.
